The full new State Pension in 2026 pays £221.20 a week — about £11,500 a year. After Council Tax, the gas bill, the broadband, and a weekly Tesco shop, the average UK retiree on the full rate has £40–£60 of genuine discretionary money each week. The kind of money that buys a coffee with a friend, a present for a grandchild, the occasional cinema ticket. It's enough to live on. It's not enough to live well on, and any retiree on the full rate will tell you so privately, even if they wouldn't say it to the kids.
Meanwhile most retirees are sitting on more empty space than they need. The kids moved out a decade ago. The garage holds a lawnmower, a tired exercise bike, four Christmas-decoration boxes, and the box from a fridge they bought in 2014. The loft has the same. The fourth bedroom hasn't been slept in since 2017. The space is sitting on £1,000–£3,000 a year of income — and most retirees never claim it because nobody told them how, and the words "side hustle" make it sound like something for people in their twenties on TikTok.
Below: the actual UK 2026 numbers, the all-important Pension Credit + £1,000 Trading Allowance interaction in plain English, why this doesn't affect Council Tax single-occupancy or Attendance Allowance, and how someone in their late 60s lists a garage on Packhood in twenty minutes from a phone or a tablet.
How much it actually adds (UK retiree, 2026)
Single-car garage on a residential street, dry, with a lockable door: £80–£180/month. The lower end (£80–£100) is small towns — Doncaster, Stoke, Sunderland, Plymouth. The upper end (£140–£180) is London suburbs and Manchester / Birmingham city centre. Most retiree-owned garages in mature suburbs sit at £100–£140/month — solid, reliable income.
Loft or attic with hatch access: £40–£90/month. Underrated. It's space you don't even walk through, and it stays empty 99% of the year holding old wedding photos and a rolled-up rug.
Spare bedroom used purely as a storage room (no person sleeping there): £100–£200/month. Not the same as rent-a-room — there's no human living in your house.
Combined: a typical 3-bed bungalow with a garage, a loft, and an empty bedroom can stack to £220–£320/month. That's £2,640–£3,840 a year of income on top of the State Pension — a 23–33% top-up to your post-tax retirement income.
Concrete: at the median, you're adding £180/mo = £2,160/yr. That's a foreign holiday, or a year of birthday and Christmas presents for the grandchildren, or 18 months of a daily takeaway coffee, or simply the difference between "we manage" and "we're comfortable."
The tax bit: Trading Allowance is the magic word
HMRC gives every UK adult a £1,000/year Trading Allowance — miscellaneous income up to that amount is tax-free and you don't even need to register for Self-Assessment. Two specific implications for retirees:
(1) A garage at £80/mo = £960/yr is fully under the threshold. No Self-Assessment, no tax, nothing reported, your tax code stays exactly as it is. The cheque arrives, that's the end of it.
(2) Spread across two adults in a household: if both you and your partner are named on the deeds, you each have your own £1,000 allowance. List the garage in your name, the loft in your spouse's name (if both legally entitled). Combined £2,000/yr of allowances — a £140/mo garage + a £55/mo loft fits comfortably with room to spare.
If you go over the £1,000 — say a £140/mo garage at £1,680/yr — you register for Self-Assessment once, and you pay tax only on the £680 above the allowance. At the basic rate, that's £136/yr of tax. You're still keeping ~£1,540 net.
What about Pension Credit, Council Tax, Attendance Allowance?
This is the fear that stops most retirees from listing. They've heard horror stories about side income tripping benefits. The honest answer requires being specific — different benefits use different rules.
State Pension itself: not means-tested. It is what it is regardless of any side income. Full stop.
Pension Credit (means-tested top-up): storage income IS treated as income for Pension Credit — the rules are tighter here. If you're on Pension Credit, list this carefully. The Trading Allowance protection works for tax but not necessarily for benefit calculations. Speak to Citizens Advice or the Pension Service before listing if you currently receive Pension Credit.
Council Tax single-person 25% discount: unaffected. The discount applies to who lives in the property, not to whether you store boxes in your garage. The renter doesn't live there — they store there. The discount remains.
Attendance Allowance / Personal Independence Payment: not means-tested. Storage income doesn't affect them.
Housing Benefit / Universal Credit: means-tested; same warning as Pension Credit. If you're on either, get advice before listing.
For the majority of UK retirees who are on the State Pension only (not means-tested benefits) plus a private pension, this is genuinely tax-free or near-tax-free additional income with no impact on anything.
The "I'm not techy" objection
Retirees ask us this almost universally: "I'm not great with apps. Can I actually do this?"
The honest answer is yes, with a single caveat: you'll need someone to take five photos with a phone (or you do it yourself if you're comfortable). Everything after that — listing, accepting bookings, identity verification, payouts — happens through a single web page that works on a tablet, a phone, or a home laptop.
What we hear most often: a son or daughter sets up the listing during a Sunday visit. Twenty minutes, including the photos. From that point on the parent only sees: an email when a renter applies, a click to accept, an email confirming the renter has paid, and a monthly Stripe payout into the bank account.
The renter visits a handful of times across the booking — most stay for 4–6 months, drop off boxes once, collect once. The host's involvement is minimal: unlock the garage, hand over a key or a code, lock up. Most retiree hosts in our data spend less than 30 minutes per booking after the initial setup.
The 10-year compounding picture
Retirees tend to think in years, not months — the 35-year-old's "side hustle" framing doesn't translate. So here's the long view.
A garage at £140/month, listed continuously, earns £1,680/year. Over a decade, with modest pricing increases tracking inflation (~2.5%/yr), that's roughly £18,800 of income. Add a loft at £55/month and you're at £25,200 over the same decade. Add a spare bedroom occasionally between bookings and you're past £30,000.
Most UK retirees on the State Pension would call £25,000–£30,000 of additional income across a decade meaningful. It's the cost of a small car, or a kitchen renovation, or two years of the kind of foreign holiday that retirees often quietly stop taking because of a single line item — the airfare, the hotel, the spending money — feeling out of reach.
Renters do change every 4–6 months, but the platform handles all of that. Most hosts in this segment spend less than 90 minutes a year on the whole operation after the first listing.
How to start (or how a family member can help you start)
If you're doing it yourself: open Packhood on your phone or tablet, tap "List your space," take five photos of the garage (one wide of the empty interior, two corners, one of the door, one from outside the property), enter the dimensions, write three sentences, set a price within the local band, verify your identity through Stripe. Twenty minutes.
If a family member is helping: they can sit next to you and walk through it. The Stripe Identity check uses your photo ID — driving licence or passport — and a selfie; that part has to be you, but the rest of the form can be filled out by anyone.
Once it's live, the platform handles the renter inquiry, the contract, the booking, the payment, and the monthly payout. Packhood emails a year-end summary every January for tax purposes (so the £1,000 Trading Allowance maths is trivial to confirm).
The take
The State Pension at £221.20/week is the floor of UK retirement income. The empty garage is sitting on a £100–£140/month addition. The Trading Allowance often makes that addition tax-free. The platform's job is to make the listing effortless and the cheque automatic.
Most retirees who eventually list this tell us they wished they'd done it three years earlier. The reason they didn't is that nobody walked them through the maths. We just did.
List the garage. Twenty minutes. The cheque is automatic by month two. Your kids will be relieved you did it.
